Simply place the shank or reamer to be measured between pins A, B, C, and D, and slide H and K together.
An inspection of the chamber-reamer will be generally satisfactory in determining the size and shape of the chamber.
If any marks of the reamer or other defects are seen in the bore, they are to be searched for, and their depths and positions noted.
Should the inspection of guns with conical chambers or slopes take place at the foundry, an examination of the chamber reamer will be very satisfactory.
This, however, might be overcome by giving the emery-wheel enough end motion to cause it to cross and recross the width of the top facet; or the reamer R may be presented to the wheel W at an angle to the plane of wheel rotation, as in Fig.
It is obvious that in this form the reamer is expanded most at the end.
But the successful use of a reamer of this kind depends upon the drill that precedes this reamer being made as nearly right as possible, so that the reamer will have little work to do.
A reamerwhose teeth may be adjusted to the required diameter.
That reamer is intended to produce a straight hole, but having once passed through a hole the reamer will be slightly worn.
There have been many attempts made to produce a reamer that should be adjustable.
Another tool for taking a very light cut to smooth out a hole and cut it to exact size is the shell reamer shown in Fig.
An adjustablereamer designed and used by the author for holes not less than 1-1/2 inches in diameter, is shown in Fig.
A chuck C is screwed onto the spindle in place of the faceplate, and a combination center drill and reamer R is gripped by the chuck jaws and set to run true.
When turning this end, either the piston reamer or the finished hole in the piston can be calipered.
When a reamer is held rigidly to a turret or toolslide, it is liable to produce a hole that is either tapering or larger than the reamer diameter.
The sizing cutter B is then used to straighten it before inserting the finishing reamer C.
The lathe is run very slowly for reaming and the reamer is fed into the work by feeding out the tailstock spindle.
The hole is then finished smooth and to the right diameter by reamer f.
The reameris especially desirable for interchangeable work, when all holes must have a smooth finish and be of the same diameter.
Two Types of Floating Reamer Holders] There are many different designs of floating holders but the general principle upon which they are based is illustrated by the two types shown in Fig.
The reamer shown at B is a fluted type with cutting edges that extend from a to b; it is used for finishing holes and the drill or rose reamer preceding it should leave the hole very close to the required size.
The bore is finally reamed to size by a reamer F held in a "floating" reamer-holder.
The reamer and holder shown to the left has a ball-shank A which bears against a backing-up screw B inserted in the end of holder C through which the driving pin passes.
To break the seal, a hollow reamer or facing tool, fitted into a drill press or breast drill, is slipped over the post.
With this reamerremove the ring of metal or flange on the post, thereby releasing the cell cover.
My tools were so inferior that I almost had to abandon the well, especially when a boring tool, a reamer was broken off in the bottom of the pipe.
These have a bolt passing through that fits into a tapering hole in the interior of the split reamerportion of the tool.
In order to insure a tight job, the holes in cam and shaft must be reamed with the next larger size of standard taper reamer and a larger pin driven in.
The function of the guide bars is to fit the valve stem bearing in order to locate the reamer accurately and to insure that the valve seat is machined concentrically with its normal center.
These are easily renewed and after running a reamer through them of the proper size no difficulty should be experienced in replacing either the old or a new wrist pin depending upon the condition of that member.
The valve seat reamershown at G will take any one of the heads shown at F.
Another form of valve seat reamerand a special wrench used to turn it is shown at C.
He glanced over his shoulder and made out that De Reamer had paused in his conversation with Mr. Chambers, and was listening to catch Carhart's reply.
And, as for the financial part, everybody knew that old De Reamer had been forced to abandon the construction work on the Red Hills extension, after building fully five-sixths of the distance.

I guess we both understand that this construction is the most important thing Mr. De Reamer has on hand these days.
But he knew he'd have to corner Daniel De Reamer first.
Great care should be taken that the reamer does not twist, as the break may be thereby deflected; and the reaming must be done also to the full depth of the hole.
The perfect alignment of the reamer is so important that where power is used this point is apt to be neglected.
The gauge of the reamer should be at least 1½ diameters.
The reamer should be applied at the center, that is, the grooves should be cut on the axis or full diameter of the hole.
The reamer he must have brought out here after he used it to enlarge the hole in my hot-air register after midnight Sunday morning.
I could see no reason for Sprague's having needed a reamer for his little job, however, and this morning I was lucky enough to get proof that Miles himself had purchased it at a hardware store on the Tuesday before Nita's murder.
In the tool chest right here, where he had also placed the reamer he had bought.
The large ends show no evidence of preparation for hafting, so presumably they were used as a hand reamer or drill.
Homemade Countersink for Wood A round or flat-head bolt can be made into a good rosebit or reamer for countersinking holes for screw heads.
The round-head makes the best reamer as more cutters can be filed in the surface and less work is required to file it into shape.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "reamer" in a variety of sentences. We hope that you will now be able to make sentences using this word.
