Intrigued! I'm waiting to see what you come up with for this one.

Nothing wrong with climb milling, frequently used in industry as it gives a longer cutter life, especially when roughing cast steels. You can often achieve better finishes too! But on the other industrial CNC machines have the stability and minimal backlash to be able to handle it.

Sadly my 45+ year old used and abused myford has a bit more than minimal backlash LOL !So I have made a start on the crankshaft while I wait for the bearings to arrive, actually started this a couple of weeks ago using a (large) bolt I had to make it from .However, I just could not get a clean cut no matter what I did and I was rapidly running out of material!

100_4952.jpg

In desperation, I made this setup with a handy lump of ally and a old Dremal to try grinding to size

WOW it actually worked !!smile o

Well not much done these last few weeks due to the lathe going tec but fixed again (for now) so on with the front housing.

100_4961.jpg

BTW this is not the original block I started with, the crankcase register was a bit under size so that will be the rear cover/intake

100_4974.jpg

Front bearing recess left .1mm under size

100_4977.jpg

100_4976.jpg

that's all the turning done just the screw counter bore and milling round the out side edges

So after searching the web and other forums, I got zero info on this engine frown so I think it's time to have a look at the insides of this mystery engine

img_20160904_205232.jpg

yes,it's a front rotary disc inlet,most people will have seen a rear rotary disc valve (that I will be using on the meteor above) but this is most unusual,although if you the name E.T.Westbury probably less so.Will screw it back together and see how it goes .

That sure is one massive crank web on the Howard. Maybe was a necessity due to front intake. And I for sure have never seen a front rotary intake. Thanks for those pictures

It might be worth contacting this chap - a veritable mine of information on such things. His website is well worth spending some time on.

Go to:
http://adriansmodelaeroengines.com/catalog/main.php

Mention my nme by all means.

Thanks for that Geoff,I have come across Adrians site before but others may enjoy looking at his excellent engine library yes

Yes onetenor,home built for certain,the patterns for casings are well done although the casting not so good surface finish,also the crankshaft is made in three pieces.

So,no sooner than I mention Mr Westbury and up pops on e-bay for sale a Westbury 5 cc KESTREL with front rotary valve smile o !!s-l1600 (11).jpg

So this week in the workshop I have finally made a start on my over engineered and unnecessarily complicated test stand to run up some of these engines I have !

this is half of it,more complication to come.

Well I'm in getting closer to possibly finishing this project smile o it might even run !imga0372.jpg

so after some nerve-wracking milling and turning I have this yes ,the crank pin will be a press fit in silver steel of .250 inch o/d,the meteor one is 7 mm so that means I will need.................

a new conrod !

So today I made an 'improved' test stand ,I have one of those clamp type mounts but always thought it could be done better as some engines did't fit so well.

These rubber buffs are great for ali. but the ones in the pic are actually stones . Wrongly packaged . my 2nd order for the rubbers ----which are black ---arrived as the blue stones despite saying rubber on packs.. Gone back with returns label. Other brands may be available. Also felt tips not shown and others which are shown

Give 'em a try
