Spent a bit of time out in the workshop today. I fly-cut the other head and cut in the Singh grooves using a modified file. I previously used a Dremel but the slots were not uniform so I heated up and bent a triangular file and used that instead. The finish is much better now and it is much easier to align the slots so that they point directly at the spark plug.

    I also drilled the holes for a second set of plugs. I did this on a scrap head just in case, but they went in really easy. The main purpose of the exercise was to make sure that the alignment was good and that the spark plugs cleared the push rod tubes. All I need to do now is to counter bore the holes from the opposite side to form the seat for the spark plug. I also need to get hold of a set of 10mm spark plugs to test everything out with.

    I cleaned up my new heads today to discover that one head had cracks. Could have sworn that they weren't there when I bought them. Guess I did not check close enough. At any rate, one head was okay. I'll pair this with the one head that I have that is also okay. Only issue is one is a type 3 and one is a bug head which means the inlet ports are massively different. Nothing that a little time with the Dremel cannot fix. Managed to get one port done, will do the other tomorrow.

    DIY dynamic balancer
    Posted on Monday, 24 April 2017
    Have long thought about building a dynamic balancer. Very useful for crankshafts and blower rotors. Easy enough to build a very simple balancer and nowadays not too much more difficult to build an accurate one. Electronic controllers are very accessi...

    As well as doing a bit of work on the engine I also decided to fit the adjustable spring plates that I got from Pat Brown.

    My old spring plates were only supposed to be a temporary measure and were more than a bit of a hack job (just check out the photos to see what I mean), so it was long overdue that they were replaced. Swapping the old and new spring plates was pretty straight forwards with the only real 'issue' being that the brake line to the caliper runs through a hole in the old spring plate so the spring plate needed to be cut to remove it. The new spring plates are slotted to accommodate the brake line. Once fitted I took some time to set the height so that I could measure up for new rear shocks. One of the rear shock bolts had come undone causing some damage to the shock. These are stock length units and are too long so it's time for some new ones to go along with the new spring plates.

    For future reference, with the rim level with the wheel arch the shock length is 15 1/2"

    I can totally recommend Pats spring plates and the other VW goodies that he makes. Top quality gear.

    Did a fair bit of work over the long weekend, just haven't had a chance to post it yet.

    First thing I did was to make a an arbor and cutter for decking heads. I considered buying one already made, they're not really that expensive, but decided to make one. For me this is half the fun of tinkering with old cars. Not just the job itself, but making the tools to do the job. I turned down some aluminium stock to fit a steel spigot. I then milled to the aluminium arbor to accept standard HSS tool stock. I ground the tool stock with a 5 degree clearance on the face and underside. I left the end of the tool as it was but the cut finish dod not come out too great on the internal diameter so will regrind this.

    The results were acceptable. a small amount of noise from the cut, mostly as my mill does not go slow enough but the finish is easily good enough and will make a nice seal with some minor lapping.

    I also fitted the exhaust valve seats into the head. I stored the seats in the deep freeze overnight and heated the heads up on the BBQ. The seats tapped in nice and easy. I then started to cut the seats but was not happy with the play in the valve guide. I initially thought this okay but after cleaning everything up there is a little too much play with the valve in the guide. I've got some new ones on order so will wait until I've fitted those before finishing the seats off
