I would like to brain storm a bit about machining bearing shells for a vintage tractor . New ones are no longer availale , the old ones ar worn to the steel backing and have way to much clearance . Altough there are a few parts sharks that sell oversized shells , a full set of shells would cost...

I guess I learned something new today . I''m quite familiar with silver soldering , mostly brass fittings on red copper , or red copper to red copper . Never had any problems with it . If the copper is clean enough I can even do it without flux . So I'm retrofitting an airco to a vintage...

I seem to have damaged MT3 of my tailstock . There's a circular burr , halfway down the bore . Most likely I have a drill with a damaged shank somewhere , and that transferred to the tailstock . I know there are special reamers to repair these , wich 'll cost you a fortune . So I was...

It's been quite a while since I fired up the furnace . This weekend I finally had the time to melt som ali , make a few moulds etc . Here's the first . This beautifull flywheel was designed by ken brunskill . He mailed it to me , and I just scaled it a little and put on some pattern draft ...

I've been using 2D cad for some 25 years now . Started with autocad for dos R12 , and used it until some years ago when I couldn't get it to run anymore on a Core i7 machine . Someone on this forum recomended draftsight , wich was free at that time . Immediatly loved it , used it for several...

So I need to bore a 1-3/4 by 2.5" ( 64*45mm) aluminium block with a length of 6" ( 150mm) . Bore needs to be parallel to at least one surface , altough that could be milled later on . Bore diam would be 1.40" ( 36mm ) . As this will be a cilinder for a gas engine , some degree of acuracy is...

Yesterday I was welding an axle for a trailer , to make a tow dolly . As it's something that goes on the road it has to be decently welded and reliable . So I took out the TIG to make the first pass . Basicly it's a tube pressed into another tube . The weld is a lap weld . Diameter of the tube...

Sorry about the odd topic title , don't really know how to describe it . I need to call on this lists wisdom . Can't seem to figure it out on my own . Picture shows an odd shaped gasket from a 26 yo pressure washer . Offcourse it is no longer available . The gasket is basicly an o-ring...

I'm thinking of making a few tangential holders . Recently got a shoebox full of hss bits so I might just as well give it a go . Much information is available on the net , so that's nota problem either . All holders seem to use thesame angle for , what's it called , side and front clearance...

It must have been more then a year since I've learned about the arduino indexer software . This was immediatly classified in my head archive as a great project , wich I would certainly do someday . I have a drawer full of those projects in the back of my head . So I started collecting all...

Guys , I 'm call on this list's wisdom . I need to solder or braze an aluminium AC condensor . The person who removed it couldn't undo the nut at the condensor side , and decided to twist it until it broke off ..... at both ends . The tube wall thickness is 1mm ( 1/32") , and altough I...

I took apart a bicyle hub with internal gearing hoping to find a ring gear to possably build an elmer's no5 geared engine . It did have a ring gear of aproximately the right size and with an even number of teeth . So that would be ok . The orbiting gear needs to be half of the ring gear ...

I think most of us have probably seen them . A little tool that allows you to use steel wire to make hose clamps . If not do a youtube search for "clamptite" . There are a couple of videos explaining how it works . I'm currently converting an old car to propane injection , so I need a lot...

Here's something I think is worth sharing . I needed to cross drill and tap 16mm hardened rods , wich will eventually be the lineair rails for the router I'm building . Only the outer skin , maybe 1mm is hardened , the core is reasonably soft . These are not the chinese rails found on ebay...

Let me start by saying I'm not an insert guy . I like my hss tools , I like to grind them , and I 'm the proud owner of a clarkson MKIII t&c grinder . Never needed inserts , and hardly use them . That said , I recently got some lathe tools with ccgt0903 inserts . CCGT is ment to be used on...

I'm gonna try to cast a T slot plate for a cnc router I'm building . I have a very good quality alloy of alum that I can melt , and I have more then enough of it . The pattern is made . It's dimensions are 425*274*26 mm . (17*11*1 inches ) . For reference , the plan is printed on A4 size...

I seem to have a minor problem when milling a pocket , or better a corner . This is a pretty deep pocket, 58mm ( 2 1/4 ") and I'm using a very long 10mm endmill . I need to use that small diam endmill , cause later on the part will be reversed and the rounded corner removed . I make a U...

Today I poured my very first sandcasting . Been casting alum for a couple of years now , mostly I simply fill all kinds of tin cans to cast rounds and squares wich can then be used on the lathe and mill . So I decided to take it one step further , make a pattern and give it a go . Turned...

It must be close to 20years ago my brother in law gave me a box they threw away at his work . He works at an engineering firm and makes drawings . The box had a full autocadR12 for dos , all the books , licences , extra's and addons . It also had a A3 flatbed pen plotter and an A3 genius...
