A Universal Valve Seat Cutter.
The sender of the following communication has been awarded the extra payment of os. this week, (2261) " MX." (Earl's Court) writes: --a" The accompanying sketch illustrates in detail and in general arrangement a tool for trueing the tops of valve seats. As a rule, when the seats have been cut it will he found that there is an upstanding film left on the top of the seat, arid for efficient working this film must be removed. It is true that tools may De purchased to effect this operation, but, as a general rule, each is made to suit some particular engine and cannot be used for any other size. An advantage of the one which I have sketched is that it is readily adaptable by the fitting of loose cutters or guide spindles to various types of engines. The handle is a plain, round bar with a tommy hole at the top. It is turned down at the. other end and screwed externally to accommodate the cutter as well as tapped and drilled internally for the guide spindle. The design of the remaining part will readily be understood by reference to
the sketch, on which I have placed no dimensions, since each mechanic will have his own ideas as to what will best suit his requirements. It, will be noticed; however, that the cutter is fitted with a couple of stop-pegs and is secured in place by a loose nut. The guide spindle screws direct into the handle.'
Mending a Broken Ford Crank.
• case.
(2262) " A.M.a." (Westport) writes: —" The following description of emergency repairs to the universal car ' may be of interest to those of your readers who have the misfortune to break off one of the lugs which support
the engine in the. chassis. Generally. such a mishap involves dismantling of the chassis before the lug can beibrazed or welded. As this is rather a long job, a temporary method of carrying on is rather valuable.
" Commence by removing those two of the bolts for the transmission case which are just near the broken lug. Obtain a couple of lengths of g in. steel bar, and bend these into the form of clips, which will embrace the side member of the main frame. Arrange one arm of each clip, so that it, will pass through one Of the two holes from which the bolts have been removed. The two ends of the clip should be screwed to a distance of about 2 ins., and, before erecting them in place, a running nut placed on each leg. A couple of steel plates are required about 5 ins. long, I in. wide, and _a in. thick. These are drilled to accommodate the two legs of the clips, and so arranged that one end of each. plate comes below the cover of the transmission case. With these plates nutted up tightly in place the vehicle will run for quite a long time without any further attentioif.
" "
If the lug which is broken happens to be on the nearside of one of the new type chassis, which is fitted with selfstarting gear, then a little rearrangement will be necessary owing to the fact that the transmission cover is secured to the crankcase at this point by studs instead of bolts. In such circumstances the two plates should be rigidly secured to the side member by means of the clips, and extra holes should 'fie drilled in them to accommodate setscrews, which will pass through the plates and take the place of the studs in the crankcase."
A Simple Wheel Puller.
(2263) " M.NI." (Earl's Court) writes : " The accompanying sketch shows details and arrangement of a substantial wheel puller adaptable to almost any size of wheel, and strong enough to outlive any that are likely to be purchased in the ordinary way. I have put no dimen.sions an the sketch, asathese Will vary according to thee requirements of a particuhrr. garage—those for a place which deals mainly with touring cars being naturally less than those for a tool in tended for use in a heavy-vehicle garage " It will be seen that it consists of a plain block drilled and tapped in the centre for the operating screw and slotted' at each side of this screw hole so as to accommodate the two claws, which are merely plain L-shaped pieces of steel, as shown in the:sketch. A number of holes are drilled through the bar, across the slots thus affording adjustment sideways for the jaws of the tool; while in those jaws themselves several holes are drilled so that their effective length can readily be adjusted.
